domain of (x^2-4)/(2x+4)

domain

\frac{x ^{2} - 4}{2 x + 4}

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

f (x) = \frac{3 x ^{2} - 8}{x ^{2} - 4}

\frac{x + 6}{x}

f (x) = x^{4} + 2 x^{2} - 1

f (x) = \frac{3}{x ^{2} - 2}

(cos (x))^{\frac{4}{3}}

What is the domain of (x^2-4)/(2x+4) ?
The domain of (x^2-4)/(2x+4) is x<-2\lor x>-2
